rich chocolate chip toffee bars

Hershey's doesn't kid around when it comes to recipes.  My husband doesn't kid around when it comes to chocolate.  After his first bite he said, "These are really good."  I said, "How good?"  His response: "Really, really good.  Hall of Fame good."  I knew it!

rich chocolate chip toffee bars  (Hershey's)
2 1/3 cups flour
2/3 cups packed light brown sugar
3/4 cup butter
1 egg, slightly beaten
2 cups dark chocolate chips or semi-sweet chocolate chips, divided
1 cup coarsely chopped nuts (I used 1 cup oatmeal)
1 can (14 ounces) sweetened condensed milk
1 1/3 cups (8 ounce package) Heath Bits 'O Brickle Toffee Bits, divided

Heat oven to 350 degrees.  Grease 13x9x2-inch baking pan.
Combine flour and brown sugar in a large bowl.  Cut in butter until mixture resenbles coarse crumbs.  Add egg; mix well.  Stir in 1 1/2 cups chocolate chips and nuts (or oatmeal); set aside 1 1/2 cups mixture.
Press remaining crumb mixture onto bottom of prepared pan.  Bake 10 minutes.  Pour sweetened condensed milk evenly over hot crust; set aside 1/4 cup toffee bits.  Sprinkle remaining toffee bits over sweetened condensed milk.  Sprinkle reserved crumb mixture and remaining 1/2 cup chips over top.
Bake 25 to 30 minutes or until golden brown.  Top with reserved toffee bits.  Cool completely in pan on wire rack.  Cut into bars.  About 48 bars.
